MMS6220

Description

trait
Dual channel: Can simultaneously monitor the shaft eccentricity of two channels.
Built-in microprocessor: Provides extended self-test function and built-in sensor self-test function.
Password protection: Operation level password protection to ensure operation security.
RS232/485 port: for field configuration and communication, can read the measured value.
Recording and storage: Can record and store the last start/stop measurement data.
effect
Monitoring and protection: The MMS6220 uses eddy current sensors to measure relative radial shaft eccentricity signals and is used to monitor and protect various types of turbine-machinery such as steam turbines, gas turbines, compressors, fans, centrifuges, and more.

argument
Input: Support eddy current sensor PR642./… Series plus preprocessor CON0X1.
Output: AC voltage signal directly proportional to shaft vibration superimposed on DC voltage, with open circuit and short circuit protection, reverse protection. Output voltage linear range: -4… -20V (supply voltage is -24V), wide range of output voltage: -1… -22V, output voltage :-12V (symmetrical measurement range at both ends). The module provides two current and voltage outputs representing characteristic values.
specification
Accuracy: The linear error depends on the type of sensor connected, such as ≤1.5% when connected to the sensor PR6422, ≤6.0% when connected to the sensor PR6425.
Response time: 15 (unspecified, possibly milliseconds).
Temperature drift: zero 200mV/100K; Sensitivity <2%/100K.
Time drift: 0.3% Max.
Error of supply voltage: <0.2%/V.
Size and weight
Size: A search result mentions a size of 23cm
Weight: Some search results mention a weight of 0.2kg
